RESUMO
AIM: Traditional apprenticeship model (AM) of teaching in invasive procedures such as temporary haemodialysis catheter (THDC) insertion can result in propagation of errors and complications. Simulation-based learning (SBL) offers standardization of skills and allows trainees to repeatedly practice invasive procedures prior to performing them on actual patient. METHODS: Retrospective cohort study of first-, second- and third-year Nephrology Fellows from a tertiary teaching hospital from September 2008 to September 2015. The intervention group (n = 9) received simulation training in ultrasound-guided THDC placement. The historical control group (n = 12) received training through traditional AM. The primary and secondary outcomes were the immediate complications and success rates of THDC insertion. RESULTS: A total of 2481 THDCs were placed in 1787 patients. Success rate of internal jugular THDC placement for AM vs. SBL Fellow was 99.8% versus 100% (P = 0.90), while the success rate for femoral THDC placement was 99.6% versus 99.2% (P = 0.53). SBL Fellows reported fewer overall peri-procedure complications (8.3% vs. 11.2%, P = 0.02) and mechanical complications (1% vs. 2.4%, P = 0.02) compared to AM Fellows. The rate of reported technical difficulty was similar (7.5% vs. 9.2%, P = 0.17). After adjusting for side and site of THDC placement, body mass index and laboratory indices, THDC inserted by AM Fellows were independently associated with increased overall peri-procedure complications (OR = 1.396, 95% CI: 1.052-1.854, P = 0.02) and mechanical complications (OR = 2.481, 95% CI: 1.178-4.810, P = 0.02). CONCLUSIONS: Simulation-based learning was associated with lower procedure related complications and should be an integral component in the teaching of procedural skills in Nephrology.

INTRODUCTION: In managing end-stage kidney disease (ESKD), older adults face a decision regarding whether to undergo dialysis or manage symptoms through kidney supportive care (KSC). This article describes the development of a patient decision aid (PDA) that is designed specifically for older adults with ESKD. METHODS: The decision context of the PDA was to choose a treatment between hemodialysis, peritoneal dialysis, and KSC. The development process used insights obtained from qualitative interviews with patients, informal caregivers, and health care providers. The PDA was then developed in English and Mandarin and was pilot-tested with patients, caregivers, and health care providers. We finalized the PDA based on feedback from pilot testing and performed a preliminary evaluation based on the International Patient Decision Aid Standards (IPDASi v4.0) criteria. RESULTS: The final PDA consists of 2 booklets and a video. During pilot testing, patients and caregivers reported high levels of ease of understanding and usefulness with ≥92.5% providing agree/strongly agree responses for the "Content"-related criteria, and ≥75% providing agree/strongly agree responses for the "Development Process and Effectiveness"-related criteria. The final PDA met 10 of 12 IPDASi v4.0 criteria. CONCLUSIONS: This PDA was found useful during pilot-testing. It will be used during renal counseling in Singapore to help older adults with ESKD and their caregivers make informed decisions on which treatment option is best for the patients.
RESUMO
BACKGROUND: The optimal vascular access strategy in elderly patients receiving haemodialysis (HD) remains controversial. We aim to report the outcomes of arteriovenous fistula (AVF) in elderly patients initiated on maintenance HD in our centre. METHODS: Medical records of 688 incident patients initiated on HD from 2010 to 2012 in a tertiary centre were retrospectively reviewed. Patients' characteristics and AVF outcomes were compared among those < 65 years (non-elderly), ≥ 65-75 years (early elderly) and ≥ 75 years (late elderly). RESULTS: There were 418 non-elderly, 184 early elderly and 86 late elderly patients. There is a higher proportion of brachiocephalic and brachiobasilic fistula created in the late elderly (24.9% vs. 37.0% vs. 41.8%, p = 0.001). The outcomes of accesses created were comparable in the 3 age groups with similar proportions of functional AVFs (80.4% vs. 79.3% vs. 75.6%, p = 0.832) and comparable 1-, 3- and 5-year primary and secondary patency rates (p = 0.351 and 0.282, respectively). However, a longer maturation time (2.78 vs. 2.86 vs. 3.72 months, p = 0.010) and a higher mean number of interventions to assist maturation of the first AVF were required in late elderly patients (0.19 vs. 0.22 vs. 0.35, p = 0.014). Following AVF creation, median patient survival in the non-elderly, early and late elderly was 65.2 vs. 55.1 vs. 49.8 months respectively. CONCLUSION: AVFs created in elderly patients have comparable outcomes compared to non-elderly patients although more interventions are required to assist maturation with a longer maturation time necessitating early access creation to allow for time needed due to maturation delay.

BACKGROUND: Despite literature suggesting conservative management (CM) is a viable option for elderly comorbid ESRD patients, the vast majority in Singapore receive dialysis. We hypothesized that the high demand for dialysis is driven by 1) lack of knowledge of CM and relative benefits of dialysis to CM, 2) adherence to physician recommendations which favour dialysis, and 3) high subsidies for haemodialysis (HD). METHODS: We tested these hypotheses via a survey, including a discrete choice experiment (DCE), administered to 151 elderly pre-dialysis kidney patients and their family caregivers. RESULTS: Results are consistent with the hypotheses: 40% (95% Confidence Interval (CI) 32-48) of patients and 46% (CI 38-55) of caregivers reported not being aware of CM, and 43% (CI 35-51) of patients and 24% (CI 17-31) of caregivers could not provide information on expected survival for dialysis or CM. Yet, once aware of CM as an option, 54% of patients and 42% of caregivers chose CM. However, if their physician recommended dialysis, 49% (CI 40-58) of patients and 68% (CI 59-77) of caregivers switched their choice. Subsidies on HD further reduced demand for CM by 6 percentage points. CONCLUSIONS: These results reveal that the high demand for dialysis is driven mostly by lack of awareness of CM as an option and by physician recommendations for dialysis over CM.
